2, the two ends of the described matrix of single condyle displacement tibia osteotomy protector of the present utility model protrude from the described two ends that stop inserted sheet respectively; thereby the lengthening of matrix design makes matrix can be supported on the cortical bone; avoided inserting dark and cause spongy bone to cross poly-injury; design ingenious; simple for structure, when horizontal osteotomy, protect, prevent many sections; the protection patient is suitable for large-scale promotion application.
3, the described matrix of single condyle displacement tibia osteotomy protector of the present utility model comprises first end, and described first end is oblique wedging end, the convenient insertion; design ingeniously, simple for structure, when horizontal osteotomy, protect; prevent many sections, the protection patient is suitable for large-scale promotion application.
Description of drawings
Fig. 1 is that the master of a specific embodiment of the present utility model looks sketch map.
Fig. 2 is the enlarged diagram of the protection portion of specific embodiment shown in Figure 1.
The specific embodiment
In order more to be expressly understood technology contents of the present utility model, describe in detail especially exemplified by following examples.
See also Fig. 1 to shown in Figure 2, single condyle displacement tibia osteotomy protector of the present utility model comprises protection portion 1, and described protection portion 1 comprises matrix 11 and stop inserted sheet 12, and the described inserted sheet 12 that stops is positioned at described matrix 11 times and is connected with described matrix 11.
For fear of inserting dark and causing spongy bone to cross poly-injury, see also Fig. 1 to shown in Figure 2, in specific embodiment of the utility model, the two ends of described matrix 11 protrude from the described two ends that stop inserted sheet 12 respectively.Be that described matrix 11 adopts the lengthening design.
Insert for convenience, see also Fig. 1 to shown in Figure 2, in specific embodiment of the utility model, described matrix 11 comprises first end 13, and described first end 13 is oblique wedging end.
Described oblique wedging end can have any suitable structure, more preferably, the end face of described oblique wedging end is inclined surface or curved surfaces, and described inclined surface or described curved surfaces connect a described side and a described side that stops inserted sheet 12 of being connected of described oblique wedging end that stops inserted sheet 12 dorsad of described oblique wedging end respectively.See also Fig. 1 to shown in Figure 2, in specific embodiment of the utility model, the end face of described oblique wedging end is curved surfaces.
For the ease of controlling protection portion 1; see also Fig. 1 to shown in Figure 2; in specific embodiment of the utility model; described single condyle displacement tibia osteotomy protector also comprises holds handle 2; described matrix 11 comprises the second end 14; described holds handle 2 comprises first terminal 21 and second end 22, and described the second end 14 connects first end 21 of described holds handle 2.
